Welcome to Desta Steel, your trusted partner for structural steel in Addis Ababa. We take pride in being a premier manufacturer and supplier, dedicated to empowering Ethiopia’s growing infrastructure. Our high-quality S355J2+N steel sheets and plates are the backbone of strong, resilient projects. We provide material that meets rigorous international standards, ensuring your builds have the integrity and durability to stand the test of time, supported by our commitment to reliable service and local expertise.
The S355J2+N grade is a fine-grained, normalized structural steel known for excellent strength. Its chemical composition includes carefully balanced elements like carbon, manganese, and silicon, while the “+N” indicates a normalization process that enhances its mechanical properties. This treatment results in a minimum yield strength of 355 MPa, combined with good toughness and weldability. This balance makes it less brittle than higher carbon steels, allowing it to absorb significant energy and resist fracture, which is crucial for safety in demanding applications.

This steel is fundamental to modern construction and heavy industry. It forms the skeleton of bridges, commercial towers, and industrial facilities, providing the essential strength for beams and columns. Beyond buildings, it is widely used for heavy-duty machinery, vehicle chassis, and mining equipment. Its reliable performance also makes it a preferred choice for storage tanks, silos, and various structural components where both strength and the ability to withstand dynamic forces are non-negotiable for long-term project success and public safety.
